AAOS 2014:胫骨Pilon骨折不宜采用联合入路

2014-03-05 佚名 丁香园

胫骨Pilon骨折后通常采用分阶段联合固定,但关于其治疗胫骨Pilon骨折效果的相关研究较少。最近有证据表明分期固定胫骨后踝可能有利于改善关节内的复位情况。但是目前尚无对前后联合固定与单独前方固定进行比较的大样本研究,因此无从得知分期联合固定是否有利于改善骨折复位。 针对此种情况研究人员进行了一项回顾性研究,选取了自2005年至2011年所有胫骨远端43C骨折的患者。

胫骨Pilon骨折后通常采用分阶段联合固定,但关于其治疗胫骨Pilon骨折效果的相关研究较少。最近有证据表明分期固定胫骨后踝可能有利于改善关节内的复位情况。但是目前尚无对前后联合固定与单独前方固定进行比较的大样本研究,因此无从得知分期联合固定是否有利于改善骨折复位。

针对此种情况研究人员进行了一项回顾性研究,选取了自2005年至2011年所有胫骨远端43C骨折的患者。根据入路不同将患者分为前后联合组和前路组。检索医疗文字和影像资料,确定其关节残余移位。关节移位分为三组(<1mm,1-2mm,>2mm)。最终愈合率与手术入路相联系。

结果共检索到116名符合条件的患,26例患者为开放性损伤。35例进行分期固定的患者在平均术后10天固定后踝,平均术后16天固定胫骨前方。其余81患者只固定了胫骨前方。21例患者的随访期只有6个月。其余随访期较长的95例患者中有24例不愈合。分期固定组患者的不愈合率较高(40% vs 19%,p=0.015)。两组间骨折残余移位大小无统计学差异(63% vs 57% <1mm,31% vs 26% 1-2mm,6% vs 17% >2m)。

由以上可知采用联合入路治疗胫骨Pilon骨折并无实际优势。联合入路可能会增加骨不愈合发生率,而骨折复位的几率亦无提高。尽管关节内复位非常重要,但过于激进的直接复位以及对所有骨折块进行固定可能会进一步导致其它并发症。
